Abstract

The water distribution system on agricultural land is one factor that determines agricultural yields. The land in the Mekar Jaya Farmer Group, Cikupa Village, Karangnunggal District, Tasikmalaya Regency is rainfed land constrained in watering the land planted with kale. The sprinkling system that has been made uses a booster pump to drain the sprinkling water in the piping system, which has been arranged in such a way and is still constrained by an uneven distribution at some points so that the watering is not optimal so in this study improvements will be made with experimental methods and simulations on the device software by changing the T joint (T knee) which has an angle of 90° to a 45° angle. The simulation results show a significant change in pressure from 3.08 Pa at a 90° T joint to 9.63 Pa at a T joint at 45°.

Abstract

A mold is a tool for printing plastic products. The way it works is by installing the mold on a plastic injection machine, and then the machine does the injection process to put molten plastic material into the mold. In the mold, there is a cavity that matches the shape of the product to be made. Before a mold can be used, it must be designed and manufactured. ATK Polytechnic of Yogyakarta has one injection molding machine with several molds available. The available molds do not yet have a design based on various information, analysis, and calculations, so this research will make a mold design that is expected to be a guideline for making plastic injection molds and is expected to be able to analyze the needs for cavities, gates, ejector systems, cooling system. In this study, the design and calculation of mold construction, including the cavity, parting line, gate, ejector, cavity plate, core plate, runner, and cooling, were discussed. The purpose of this study is to determine how to design a basic mold construction with a two-mold plate system, with the resulting product being a tensile test specimen. The result of this tensile test specimen mold design is a mold base design drawing with a mold size of 350mm x 500mm x 255mm, the number of cavities being 4 cavities per mold, and the volume of the tensile test specimen mold being 33.0122 cm3.

Abstract

Air conditioner (AC) is a tool used to condition the air in a room or product temperature. Air conditioning in the form of regulating temperature, regulating cleanliness, and adjusting the air flow rate. The purpose of this study is obtain the comparison of the coeffisient of peformance (COP) and Energy Efficiency Ratio (EER) values in inverter split air conditioners with a capacity of 1/2 pk using R-22 and R-32 refrigerants. The method used in this study is observation and exsperiment , data collection based on test results using ac trainers that we make, using different refrigerants or refrigerants, namely R-22 and R-32 refrigerants, by varying the rotation of the evaporator fan in low, medium, and high modes. The results of this study are in the air conditioner (AC) split inverter capacity of 1/2 pk using R-22 refrigerant the highest coeffisient of peformance (COP) value obtained by 5.05 at the turn of the high evaporator fan and coeffisient of peformance (COP) in the air conditioner (AC) split inverter capacity of 1/2 pk using the highest R-32 refrigerant obtained by 7.37 in the high evaporator fan speed variant. Then the Energy Efficiency Ratio (EER) value produced in the air conditioner (AC) split inverter capacity of 1/2 pk using R-22 refrigerant is 17.22 Btu / h, while in the air conditioner (AC) split inverter capacity of 1/2 pk using R-32 refrigerant obtained 25.13 Btu / h. So that the performance of air conditioner (AC) split inverter capacity of 1/2 pk with refrigerant R-32 has better performance compared to air conditioner (AC) split inverter capacity of 1/2 pk with refrigerant R-22.

Abstract

Mesin pendingin adalah sebuah alat siklus yang prinsip kerjanya hampir sama dengan mesin kalor yang menggunakan fluida kerja yang berupa refrigeran. Siklus refrigeran yang paling banyak dipakai adalah daur refrigeran kompresi uap yang melibatkan empat komponen dasar yaitu kompresor, kondensor, katup ekspansi dan evaporator. Tujuan dari penelitian ini untuk mengetahui berapa besar nilai perpindahan panas konveksi optimal dan nilai nusselt number tertinggi. Pada penelitian ini metode yang digunakan adalah pengambilan data berdasarkan hasil pengujian dengan menggunakan traniner AC yang kami buat, menggunakan bahan pendingin yaitu refrigerant R32 dengan variasi putaran kecepatan fan kondensor dalam posisi high. Hasil penelitian pada air condisioner (AC) split konvensional dengan kapasitas ½ PK  didapatkan nilai tertinggi pada jarak waktu 45 menit, koefisien perpindahan panas konveksi tertinggi didapat sebesar 2,50521 W/m.°C pada kecepatan fan kondensor 4,4 m/s sedangkan koefisien perpindahan panas konveksi terendah didapat sebesar 0,34923 W/m.°C pada kecepatan inlet 1,34 m/s sedang kan nilai nusselt number tertinggi didapat sebesar 0,26938 pada kecepatan fan kondensor 4,4 m/s sedangkan nilai nusselt number terendah didapat sebesar 0,3717 pada kecepatan inlet 1,35 m/s.

Abstract

Maintenance adalah proses pemeliharaan atau perawatan terhadap sesuatu asset berupa barang bergerak maupun tidak bergerak. Dalam bisnis alat berat, maintenance adalah serangkaian proses yang bertujuan untuk memastikan mesin atau peralatan lainnya dapat digunakan secara berkelanjutan dan efisien dalam jangka waktu yang dikehendaki. Rusaknya recoil spring pada excavator PC1250-8 merupakan kasus yang sering terjadi, disebabkan kondisi unit yang baru belum dilengkapi dengan komponen tambahan berupa penutup (cover) sehingga dapat mencegah masuknya kotoran ke recoil spring. Akibatnya adalah rusaknya komponen recoil spring disebabkan oleh tanah, batu/krikil, dan kotoran lainnya yang masuk dan mengendap di sekitar area gerak (inner frame). Dari persoalan tersebut maka didisain suatu perancangan cover untuk mencegah kotoran masuk ke dalamnya. Proses perancangan ini menggunakan alat bantu software Autodesk Inventor 2020.

Abstract

Due to limited resources and high expenses, simulation is a problem-solving technique that can assist in reducing the number of experimental experiments. The chosen combustion model significantly influences the simulation results. The practical strategy and research methodology on a 155.1 cc gasoline engine that uses combustion parameters requires using various combustion model parameters. In this study, a 115.1 cc gasoline engine's combustion process will be simulated, along with its production of exhaust gases in the combustion chamber. For a 155.1 cc petrol engine, our simulation uses SolidWork 2022 to identify the largest performance zone. The most significant performance zone for a 155.1 cc petrol engine is determined by our simulation using SolidWorks 2022. The output data is then compared at 5000, 6000, 7,000, 8,000, 9, and 10,000 revolutions per minute. According to the simulation results, a crank angle of 720.50 degrees and a rotational speed of 5000 rpm produce the ideal peak pressure for the best performance zone, which is 1497.20 kPa.

Abstract

One of the vehicle systems that must be designed to provide safety and comfort while driving is a good steering system. One of the characteristics of a good steering system is the balance of the rotation of the steering system when used. At this time the problem with the steering system is the motorbike steering wheel which is difficult to balance and control due to damage to the steering area, especially on the Honda CRF type 150L motorbike. So this research will look for a solution to the problem. This research uses the method of literature study, field study, observation and discussion in the data collection process. The purpose of this study is to analyze the causes of damage to the steering wheel, make a design plan for composite fastener nuts as well as covering the steering area, and create a steering system maintenance program for the steering system area. With the results of the analysis that has been carried out on the steering system in the steering area, alternative solutions are obtained to prevent damage to the steering wheel by designing the steering wheel adjustment nut and maintaining the steering system in the steering area.
